@A MyEpilepsyTeam Member , Like the AI message mentioned, have you ever had seizures in your sleep? Most but not all of my seizures happen in my sleep. Sometimes I do & sometimes I don’t know that I’ve had a seizure, unless I notice something odd or someone witnesses it, like my Mom or stepdad, who I still live at home with. Numerous times I have woken up & noticed something odd & determined that I probably had a seizure. One time I woke up confused & was feeling around on my bed & then I snapped out of it & I assume it was a seizure. So you might mention it to your doctor if this might be the first time you’ve had a seizure in your sleep. Take care. Your friend in Texas, Becky
